Mk4 Golf Rear Speaker Tips?

Hi there, I have a MK 4 Golf 1.4 S. It has the factory front 2 speakers in and and I would like to install 2 speakers into the rear.

I have installed this head unit and have surprisingly good sound from the front 2 factory speakers. http://www.amazon.co.uk/Sony-CDX-GT450U-Head-Unit-Front/dp/B004I1JMT2

I would like to install 2 speakers in the rear passenger doors where they are designed to go. A Beta system was present before, so there is no wiring present.

My needs: 2 rear speakers, decent sound quality. Budget ÂŁ50. Nothing else.

Please can you give me tips on the process of how to wire the speakers in, and which speakers would be best suited to my needs. For example, components vs coaxial. Or would I be better off doing something completely different? Like I said, I just want some speakers matching the quality of the front ones at least, in the rear of my car

Many thanks

You can get rear door wiring looms on e-bay from between ÂŁ9 & ÂŁ15 a piece, but not sure they'd be any good, as some of the wiring between the door & the head unit would more than likely be missing. You'd probably need to buy the door card innards, that house the window motor & the speaker too, to get everything like OEM. I've seen them for about ÂŁ25 a piece, which kinda blows the ÂŁ50 budget...

i've done an OEM rear speaker install on my golf. It to had a beta unit from new and now has a gamma until I can afford something better. I added the rear speaker wires to the ISO plug on head unit end then ran the wires round through the sills to the b pillar. I used some b pillar connectors takes from a scrapped gti and cut out the speaker connections and fitted into my existing b pillar connector (there are blank sockets that the pins go in to) then fitted new rear door looms that had the speaker wiring and finally OEM speakers and tweeters. This now is identical to an,OEM setup so in the future if/when,I want to upgrade I can just get the conversion wires and speaker spacers to fit aftermarket kit. There's a brief description on my build thread and if you need a hand pm me. It probably cost about ÂŁ30 all in with some parts from eBay and some from scrappy.

Hi thanks a lot for the replies really appreciate it. sorry forgot to mention. Budget has changed :p Change of idea. fresh install. 4 speakers, (2 front, 2 back) and an amp in the boot. The package I linked to seems adequate, and for that price decent. If nothing is holding me back.......Im going for it! what you think?

...Im going for it! what you think?
I think as I already said they'll sound worse than what you've already got in there.Amping up the stockers will sound good.Or another idea will be to buy some GOOD components for the front (say ÂŁ150) and put the old fronts in the back,just amp the fronts though if you're looking for any sort of real sound quality and run the rears at a low level as rear fill.

thanks I'll have a long hard think about it

Well, 9 months down the line and still no progress! but xmas is coming... so im getting it done. Imagewerx this i am going down your recommended route. I am going with 2 components in the front, and put the current front OEM speakers in the rear. and just amp the 2 front components with 2 channel amp.

The components I'm going to get are these: http://www.ebay.co.uk/itm/251592243349?_trksid=p2060778.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT

Looks like they come with the spacing adapter things. (SAK-3103)

Not found an amp yet but the speakers are 80watts RMS each, so that makes 160watt RMS total for them. So I'm looking for an amp of between 75% - 150% of 160 RMS if that's correct? 75% = 280watt and 150% = 400 watt. So somewhere in-between there.

Now a question when doing the rears. I will obviously have to buy some new speaker wire that is long enough to run from the rear to the headunit. I am just wondering whether i will need some of the adapters (SAK-3103) as well even though they will be OEM?

Hope I'm heading in the right direction. Thanks...from an obvious first timer...!

Quart speakers are not too bad for sound quality,but tend to be lacking in any real bass (as most sound quality speakers do) so only really work well when high passed and used with a sub.Too much maths is making my brain hurt this late at night :wacko: ,but a 400 watt amped turned down will always be better than an 80 watt amp turned all the way up.I have 80 watt RMS horn speakers in the front of my car and they're driven by a Kicker 2 X 250 watts RMS amp,so massive amounts of headroom and almost impossible to drive into distortion.

Oh and more or less any old speaker wire (16 SWG is about right) for the rears as they're not being amped,and from a distant memory the speakers should just go straight in without any other mounting hardware.

Remember to look for speaker sensitively too, theres a huge benefit to be made from getting a 90db sensitive set over an 80db set.. this especially helps when running from a low power source (>300rms) IMO, that kit doesnt give you RMS figures either, I cant see it being 1200RMS

(didnt read the last few post my bad :p )

They seem a tad expensive for the specs, maybe because of the "vw" custom gimic, i agree you should just amp the OEM speakers, maybe do that first before you spend an extra ÂŁ100 on the rears and see how you like it, a lot of people dont think it is (myself not included but each to their own) a decent amp will make it crystal compared to before.

Sorry to be annoying and asking instead of checking inside myself, (but its a bit nippy out at the moment!). I am wanting to move the front OEM speakers to the rear in the vacant space for them. I am assuming i cannot just 'pick them up and move them to the location' as the wiring will not be long enough to do that?

How will i get around this? thanks

Yes,you can use the unoccupied positions in the ISO block using standard VW repair wires.Or you can just splice into the green and purple pairs in the new unit's loom.
I will use the unoccupied position. And the vw repair wire goes into the ISO block (just clips in?) and then the speaker wire connects to the other end of that? Will have a look on ETKA in a bit to find part number for vw repair wire. couldn't see any in ebay. Thanks for your help, starting to be clearer now

Couldnt find on ETKA. Just buy 2 of these then and they'll fit right into the ISO block? http://www.ebay.co.uk/itm/GENUINE-VW-VOLKSWAGEN-REPAIR-WIRE-0-63-000979009E-/330921841542?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item4d0c7a9386

there are so many variants of the repair wire here tho! not sure which to get http://www.passatplus.de/umbauteile/stecker/stecker.htm
They're for different types of plug and without having both in front of me I can only narrow it down to half a dozen or so.You could also take a trip to the breakers yard and cut off the relevant ISO plug from a car that's got rear speakers,cut off your two way,and join on the new front wires to your existing ones and then the rear ones to the new wires.

Just got some pics to help me explain and hopefully you might be able to identify the type of repair wire i need. because i've found another version of it on ebay now. http://www.ebay.co.uk/itm/GENUINE-VW-REPAIR-WIRE-PART-NUMBER-000979133E-/380941074004?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item58b1db7e54

Thanks

The 'what's this?' is the lighting plug for the original single CD player.But as I said above,I can't tell from small 2D photos like that if it's right or not.Why not try what I suggested earlier and get yourself a 4 way speaker ISO,you could even take the pins out and put them into yours if you want to keep it neat with less soldering.
